Characterization of the bundle thickness, DB, and pore size, ξ, distribution at various R values. (A) EM images of the actin-only (a) and R = 1(b) samples. (Scale bar, 200 nm.) (B) Two-dimensional map of the particle trajectories to demonstrate ξ and the degree of heterogeneity at R = 0.03 (a) and R = 1(b). (Scale bar, 1 μm.) (C) The distribution of pore sizes at various R values for cA = 11.9 μM measured with MPT (solid red) and confocal microscopy (CF, striated blue). We observed both the mean and the width of the distribution of ξ increasing as R increased. P(ξ), normalized probability.
